The Undercover Man (March 21, 1949)

The Undercover Man is a tightly paced, hard-driving procedural that grabbed me from the first few minutes and never let go. It’s a fictionalized version of the federal case against Al Capone in which Capone not only never appears onscreen, his name is never spoken aloud. He’s referred to simply as “The Big Fellow,” even in newspaper headlines.

Director Joseph H. Lewis’s two most enduring films — Gun Crazy (1950) and The Big Combo (1955) — lay ahead of him, but he’d been working in Hollywood for more than a decade and had directed more than two dozen pictures (mostly westerns) before he directed The Undercover Man. The only one I’ve seen is The Swordsman (1948). I never thought I’d enjoy a Technicolor swashbuckler starring Larry Parks that took place in the Scottish highlands, but I really enjoyed The Swordsman.

Lewis made stylish films with great pacing. The Undercover Man has a standard story and stock characters, but it kept me involved because it’s paced really well. It’s loosely based on the career of Treasury agent Frank J. Wilson, who was involved with the 1931 prosecution of Al Capone and investigated the Lindbergh kidnapping. The film takes place in the present day, however, and isn’t specifically about Capone.

Glenn Ford plays a fictionalized version of Frank J. Wilson, named “Frank Warren.” The title of the film is misleading, since Warren doesn’t go undercover. The only “undercover man” in the film is a contact of Warren’s who’s gunned down by mobsters in the early going.

The film sticks to the tax evasion angle of the Capone case, and most of the drama involves Warren poring over financial records and butting heads with The Big Fellow’s crooked attorney, Edward O’Rourke (Barry Kelley). So if you’re looking for an accountant who picks up a shotgun and blasts mobsters by the dozen, like Charles Martin Smith does in Brian De Palma’s The Untouchables (1987), then you might find The Undercover Man pretty boring.

But if you’re looking for a hard-nosed flick about cops and criminals made in a semi-documentary style, you can’t go wrong with The Undercover Man.
